Rapid preparation device for small particle size gunpowder stabilizer content analysis sample

Abstract

The invention discloses a device for quickly preparing a stabilizer content analysis sample of small-grain-size gunpowder. A semi-circular material groove is formed at the bottom of a U-shaped feeder base of the device; the material groove passes through two sides and forms a discharge hole and a screw channel; a feeding screw bracket is in fastening connection with one side of the screw channel of the feeder base; an internal thread through hole which corresponds to the discharge hole is formed in the feeding screw bracket; a feeding screw is screwed in the internal thread through hole and corresponds to the discharge hole; a semi-circular upper material groove with corresponding hole diameter is formed on the lower part of a feeder upper cover and matched with the feeder base to form a hole channel in which powder grains are accommodated; and a cutter is arranged in the discharge hole of the feeder base. The invention has the advantages that: the small-grain-size gunpowder can be continuously cut in a continuous feeding and discontinuous cutting mode; by designing the discharge hole and the material groove with different hole diameters, gunpowder with different diameters can be processed; and the device is applicable to preparation of a plurality of kinds of gunpowder.

Description

technical field [0001] The invention relates to a rapid preparation device for analyzing the content of a small particle diameter gunpowder stabilizer, in particular to a device for cutting small particle diameter gunpowder by means of continuous feeding and intermittent shear force, and belongs to the technical field of explosives . Background technique [0002] The accuracy of the content analysis of stabilizers and their derivatives in nitrate gunpowder is an important experimental basis for the reliability of storage life prediction. In order to accurately obtain the content of stabilizers and their derivatives, it is necessary to process the gunpowder into thin flake samples in order to fully extract the target substance with a solvent. Therefore, the preparation of samples is an important link. For gunpowder with a large powder size, it is usually cut manually with a blade, but for powder particles with a small diameter (below Φ3mm) and an aspect ratio of less than 1,...

AI Technical Summary

Problems solved by technology

For gunpowder with a large powder size, it is usually cut by hand with a blade, but for powder particles with a small diameter (below Φ3mm) and an aspect ratio of less than 1, it is extremely difficult to cut by hand, and the uniformity of the test pieces cut by hand is poor. low efficiency

For medicine particles with high hardness that cannot be cut at all, the whole medicine particles are decomposed and destroyed by saponification under the action of strong alkali.
